Claims

exact text as granted — not AI-modified
We claim: 
     
       1. A fluorosulfatoperfluoroalkanesulfonic acid halide of the formula ##STR37## wherein R f  is F or perfluoroalkyl having 1-10 carbon atoms, X is Cl or F, and n is a number from 0 to 7. 
     
     
       2. An acid halide as in claim 1 wherein X is F. 
     
     
       3. An acid halide as in claim 1 wherein said perfluoroalkyl has 1-8 carbon atoms. 
     
     
       4. An acid halide as in claim 3 wherein X is F. 
     
     
       5. An acid halide as in claim 1 wherein said perfluoroalkyl has 1-3 carbon atoms. 
     
     
       6. An acid halide as in claim 5 wherein X is F.
